Tight Sample Complexity for Low-Degree and Sparse Boolean Polynomials
Jasper van Doornmalen, Mathieu Molina, Victor Verdugo +1
Motivated by the optimization of bounded binary black-box functions, we study the problem of learning polynomial surrogates over the Boolean hypercube. To ensure that optimizing th…

Explaining k-Nearest Neighbors: Abductive and Counterfactual Explanations
Pablo Barceló, Alexander Kozachinskiy, Miguel Romero Orth +2
Despite the wide use of -Nearest Neighbors as classification models, their explainability properties remain poorly understood from a theoretical perspective. While nearest neigh…
